UNITED STATES PATENT OFFICIAL FREl RIC C. WEIR, OF CINCINNATI, OHIO.

RAILROAD-FROG.

SPECIFICATION forming part of Letters Patent No. 236,129, dated December 28, 1880,

Application filed August 30,1ss0. (No model.) i

To all whom it may concern:

Be it known that I, FREDRIO G. WEIR, of Cincinnati, Hamilton county, State of Ohio, have invented an Improvement in Railroad- Frogs, of which the following is a specification.

My invention relates to the class of frogs known as and termed spring or movable Wing-rail frogs, and is designed as an improvem cut on Patent No. 220,264, dated October 7 1879.

The object of my invention is to provide a sufticiently flexible and durable spring for closing the movable wing rail or rails and holding them in the position designed for them, and one that shall be sufticiently out of the way of objects as to prevent any of the movable machinery from striking it, and also to provide a spring that cannot be blocked or clogged by either ice, snow, or sand; and the fact of the movement of this spring being outwardly is apretty sure safeguard against these objections.

In the accompanying drawings, Figure 1 is a plan of a frog embodying my improvements.

Fig. 2 is an enlarged view, showing the spring,

attached to the main point-rail, with the hook end of the spring passing through the slot in the heel end of the spring wing-rail. Fig. 3 is a transverse section of the rail on line a; 00, Fig. 2.

O is the spring, and is made booked at the flexible end, Where it passes through a slot in the wing-rail A, to insure more flexibility, and is secured to the Web of the main point-railB by holder and bolt 0; but it is obvious that it might be attached as shown at D, though the manner first described is preferable.

Having described my invention, I claim- A spring-rail frog having a spring, 0, flexibly connecting the movable wing-rail with a fixed part of the frog and adapted to control the action of the movable wing-rail, substantially as specified.
